Details

The precision and reliability of the INA326EA/2K5 instrumentation amplifier are unmatched, thanks to its fixed gain of 2.5 and low-power design. With high common-mode rejection and high input impedance, this amplifier is well-suited for applications that require exceptional accuracy, such as sensor signal conditioning, data acquisition systems, medical instrumentation, and precision audio equipment. The device's maximum input offset voltage of 75µV and maximum input offset current of 50nA ensure precise measurements, while the low input bias current of 5nA further enhances its performance in critical applications. Operating on a wide supply voltage range of ±2.25V to ±18V, the amplifier can function reliably in diverse power environments. Its temperature range of -40°C to 85°C allows for consistent operation in varying temperature conditions. Additionally, the amplifier's 8-pin SOIC package simplifies integration into different circuit designs, making it a versatile choice for a range of applications that demand high accuracy and reliability
